Aa. Postnikov et al., STRATIGRAPHY OF CAMBRIAN DEPOSITS IN THE OZERNY ORE CLUSTER (WESTERN TRANSBAIKALIA), Geologia i geofizika, 38(3), 1997, pp. 608-619
Neu data are given on biostratigraphy of the Lower Cambrian Oldynda Fo
rmation of the Ozerny ore cluster, Western Transbaikalia. The formatio
n is subdivided into eight members; it dates from Atdabanian-Botomian,
with the boundary running between stages along the base of the Nazaro
vo member. It is concluded that the scheme of the stage dismembering o
f the Lower Cambrian of Siberia may be extrapolated to Transbaikalia.
New species of archeocytes are described: Tumulocyathus postnikovi Zhu
r., Dupliporocyathus? terleevi Zhur.
